Paliperidone Impurity 156 CAS 3109322-10-0 chemical structure

Description

CATO supplies Paliperidone Impurity 156 (CAS 3109322-10-0), a pharmacopoeial impurity reference standard (molecular formula C9H11BrFNO, MW 248.09 g/mol) used for the identification and quantification of trace impurities in APIs.

Paliperidone Impurity 156 (C9H11BrFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Paliperidone Impurity 156 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
